Ma Rong
Ma Rong, courtesy name Jichang, was a Chinese poet and politician of the Eastern Han dynasty. He was born in Youfufeng in the former Han capital region, in modern Xianyang, Shaanxi Province. He was known for his commentaries on the books on the Five Classics, and the first scholar known to have done this. He also developed the double column commentary while doing it. His main students were Lu Zhi and Zheng Xuan.
He was suspended for ten years due to critical comments. Eventually he was restored to the Governor of Nan Commandery. His biography appears in the Book of Later Han. He wrote the Rhapsody on Long Flute ; the Song dynasty Classic of Loyalty, patterned after the Classic of Filial Piety, bears attribution to his name.
